This is a jacket pinch trim die for jackets longer than 1-5/8 inches, or larger than .458 caliber (diameter), or for extremely heavy wall jackets.

The die will work with any caliber, however. It is built for the heavier bullet jackets and greater length adjustment than the standard trim dies. (A standard trim die uses the -S type die and punch with adapters to fit the larger -H press. This permits the use of the same die, without the adapters, in an S-press. The custom version is a "magnum" style, which does not use -S components, and is entirely dedicated to the larger ram and punch holder of the Hydro Press and Mega Mite press.)

The internal punch has a threaded nut which rests on the shelf or step inside the press ram when the ram is raised. As the ram comes down, the knock out bar through the ram contacts the end of the internal punch and stops it from moving down with the die. This ejects the cut jacket from the die.

The jacket is pushed by hand into the die when the ram is raised to the "load" position, which allows the internal punch to drop to the internal step or shelf and stop. Where it stops, relative to the die bore, depends on your setting of the nut on the punch. The punch and nut rest on the shelf, setting a fixed distance from the die mouth to the "working" end of the punch inside the die.

Any portion of the jacket that won't fit into the die is sheared off when the ram is raised and the jacket enters a conical top punch, expanding and pressing the jacket material between the punch cone and the sharp mouth of the die. The press needs to be set up so that the ram stops and cannot move any further up, and then the top punch is adjusted downward, without a jacket in the die, until the punch and die just barely touch.

That prevents driving the punch into the die cavity and peening over the sharp edge. If the edge of the punch should be damaged by improper adjustment, it is easy to fix by cutting or grinding off a small amount of the die face, restoring the sharp edge. This is best done by using a tool and cutter grinder, to maintain a sharp squared edge on the die cavity. If the jacket is not scored deeply, but is mashed or sticks instead, it probably means that at some point the punch was driven into the die mouth and the mouth edge is peened over. This requires grinding the die face lightly before any further work can be done.

If the die is returned to us, it will be fixed for just the cost of the return shipping and insurance cost back to you. The die can be ground hundreds of times before it gets too short, since so little is taken off in one sharpening.

Jackets need to slip by hand into the die but cannot be so loose that they are not supported by the die walls. In other words, a .458 jacket would not be trimmed using a .500 die, nor would a .284 jacket work for trimming in a .308 die. In either case the jacket would probably buckle, get a lopsided trim, expand in a random manner within the die so that they would not fit the next bullet swage die for their caliber, and so forth. The tool works with the jacket designed to be trimmed, not with others.

Sometimes a given caliber of jacket may already be oversized, since bullet jackets normally used for hand swaging operations are undersized, to allow them to expand and then spring back toward the core, gripping it firmly. A .308 jacket for instance is usually about .3065 inch diameter before the core is seated.  Since the trim dies are made using normal jacket specification, if you were to obtain some source of .308 jackets that were .3075 inch diameter obviously the trim die would not fit them if it was not built using them for testing.  It would work with normal .3065 jackets.

If you have a jacket that is NOT being furnished by us at the time the die is built then PLEASE save the potential delays, costs, and frustrations by sending some samples of the jacket you really intend to use.Ten We can trim it, discover the correct bore diameter, adjust the shear angle for the right material hardness, temper and thickness, and thus guarantee that the die will trim your jacket when you receive it.

Otherwise, we can only guarantee it trims the jacket we used here to test it. The trimmer normally will, in fact, handle a variety of jacket thicknesses, but it is only guaranteed to trim the jacket used to build and test it. The others are a bonus in most cases. A .224 jacket trim die usually will trim both our commercial jackets and those made from fired 22 LR cases for example. But the ET-2-HC would only be used with jackets larger than .458 or longer than 1.625 inches. Otherwise the regular ET-2-H would be used.
